The skull of Mosasaurus hoffmani. From Lingham-Soliar 1995.
On my first trip to the Inversand marl pit in Sewell, New Jersey, I didn't find the wonderfully preserved Dryptosaurus skeleton I had been dreaming of. I picked up a number of Cretaceous bivalve shells and Paleocene sponges, but other than a few scraps of "Chunkosaurus" my excavations didn't yield very much. Before my paleontology class left the site, though, we took a walk by the spoil piles - great green mounds of sediment that ha........ Read more »

Three months ago, I ran the post that appears below. This post got lots of comments, and there were a fair number of misunderstandings, so let me up-front here make clear what I mean by facilitated communication in the hopes these misunderstandings do not occur again. We teach our children many skills by using hand-over-hand techniques. I'm not talking about teaching your child how to type, how to hold a pencil, how to do things. I'm talking specifically about the facilitated communication as Bi........ Read more »

Our planet is an intriguing concoction of variables that meld together for successes spanning the organization of life (species, populations, communities, and ecosystems). It is literally an evolutionary process that is ecologically driven. And as a genotypic sex determined species, we seem to have an inherent fascination with the mysterious adaptive significance of environmental sex [...]... Read more »

The influenza virus neuraminidase (NA) protein is required for virus release from the cell, a property exploited by the antiviral drugs oseltamivir (Tamiflu) and zanamavir (Relenza). During clinical testing of oseltamivir in 2001, some individuals shed drug-resistant viruses with an amino acid change from histidine to tyrosine (H274Y) in NA. Such viruses are not inhibited [...]... Read more »

I saw this and could think of nothing but the alien from the movie Predator.
This is a frontal view of the head of a male Branchinecta brushi. This species of fairy shrimp is interesting in several ways. First, it is a species new to science, having just been described in a paper last week.
Second, this is one of the two highest crustacean species on the planet. There is one other crustacean found in the same pools that B. brushi is found in.
I also have to give this paper credit for the bes........ Read more »

How the hell did seals get into Lake Baikal?

There's been much excitement about the latest big genetic study into autism, published in Nature : the grandly titled Autism Genome Project, brought to you by a crack team of no fewer than 177 researchers.For a good summary of the research take a look here, and for a longer account here. In a nutshell, the authors examined DNA from almost 1000 people with an autism spectrum disorder. They were looking for deletions and duplications of segments of DNA: so-called copy number variations (CNVs). A C........ Read more »

Our brains’ internal representations of ourselves are not, it would appear, quite as accurate as one would have thought.
That, at least, is the conclusion of paper which just came out in the dangerously-acronymed PNAS*.
To introduce the subject, then, let’s agree that it’s important for the brain to know where all our various physical bits are. [...]

Extreme dieting and fasting can increase the risk for binge eating. For some individuals, binge eating seems to be a compensatory mechanism for weight restoration. The variability in binge eating behaviors following food restriction has been unknown.

Repost from March 26, 2010.I recently wrote a research-based blog on facilitated communication. It was a rather long article, I'll admit, but I thought it important to provide as much information about facilitated communication and what the overwhelming majority of studies and meta-analyses showed regarding it. It has, despite its popularity in some sectors of the autism community and its fervent supporters, been shown that the communication comes not from the individual who is nonverbal but fro........

A drop in the bucket - a massive pile of bison skulls about to be ground into fertilizer, photographed circa 1870. From Wikipedia.
From almost the very start, wolves were not welcome in Yellowstone. When the national park was established by the United States government in 1872 the bison population had crashed - a victim of westward expansion, the fur trade, and the desire to deprive native people of an animal important to their existence - leaving the area's wolves little recourse but to beg........

One of the questions addressed in this space is, "what makes a particular condition susceptible to quackery?" Some of the common features we've seen over time are: Diverse and protean symptoms: fatigue, "brain fog", diffuse pain, and other vague symptoms are often used as diagnostic criteria for controversial entities such as morgellons and chronic Lyme disease.
